Title: Cleaving saw for cleaving slaughtered animals
Inventor: SYRE MANFRED
IPC: A22B5/20
Filed: 1983-05-27
Abstract: Slaughtered animals are to be cleaved along the plane of symmetry. The saw blade of the cleaving saw must therefore be adapted to the course of the backbone of the animal to be cleaved. As in many cases the animal carcase is suspended in an inclined position on a conveyor and in addition irregularities in the anatomy of the animal also have to be compensated, the cleaving saw according to the invention is additionally pivotable about a horizontal axis to achieve two degrees of freedom. During cleaving, the saw is moved from an upper position into a lower position. At the same time, the possibility exists of, by guiding the centring device (2), moving in or counter to the running-through direction of the animal carcase (35), and at the same time pivoting about the horizontal axis (36). The centring device (39) arranged in the region of the head end is aligned with the upper centring device (2) and becomes effective when the cleaving saw has reached the central region of the animal carcase (35). The head-side region is brought into a position of symmetry by the spreading fingers which can be inserted into the armpits formed by the front legs. <IMAGE>

Patent DE-3327879-A1 (DE)
Inventor: KESSLER HEINRICH DIPL PHYS
IPC: H03M1/00
Filed: 1983-08-02
Abstract: An integrated semiconductor circuit which contains both a microprocessor as well as an analog-to-digital converter. Two D/A converters are allocated to an A/D converter. One of the D/A converters generates a internal base potential from an externally supplied fixed base potential and an externally supplied fixed reference potential under the direction of the microprocessor. The other one generates a internal reference potential from the two external potentials. The two internal potentials form the reference voltage which serves for the A/D conversion according to the principle of successive approximation. By so doing, the same circuit can be controlled by measuring points having different voltage ranges without the converter having to be provided with additional comparison stages. These are involved in comparison to the A/D conversion to be applied and serve the purpose of increasing the resolution.

Title: Method for heating and cooling a phthalic anhydride separator, and plant for separating phthalic anhydride
Inventor: SAFFRAN HELMUT DIPL ING
IPC: C07C51/573
Filed: 1983-10-29
Abstract: In the method for heating and cooling a separator for obtaining phthalic anhydride from a stream of gas, heat is supplied, to, and removed from, the separator periodically in succession by means of a hot heat transfer medium and a cold heat transfer medium, respectively, and the hot, or cold, heat transfer medium is circulated and reheated, or recooled, outside the separator. The method is characterised in that towards the end of the heating phase heat is removed from the hot heat transfer medium which is returned from the separator, this heat is stored, and the stored heat is returned to the hot heat transfer medium at the beginning of a subsequent heating phase, before the hot heat transfer medium is reheated. Temperature peaks in both the circulating hot and the circulating cold heat transfer medium are reduced. A reduction in the steam requirement peaks during reheating of the hot heat transfer medium avoids adverse effects of the self-sufficiency with regard to energy in the production of phthalic anhydride in the explosion zone.
Patent DE-3340378-A1 (DE)
Title: Method for the transmission of information, in which the signals are coded by means of the magnitude of the amplitudes of the half- cycles or periods of a sinusoidal alternating current
Inventor: DIRR JOSEF ING GRAD
IPC: H04J7/02
Filed: 1983-11-08
Abstract: An unfavourable signal-to-noise ratio and a pulse-dependent frequency band expansion occur during pulse-amplitude modulation (PAM). High frequencies are required for the digital binary coding of signals using the half-cycles or periods of an alternating current and the characteristic states of a low and a high amplitude value. In the case of the invention, the samples taken from pulse-amplitude modulation of signals which extend from unipolar/binary to continuous are coded by means of the half-cycles or periods of an alternating current, and a plurality of alternating currents of lower frequency, having a predetermined mutual phase shift, are also provided for the taking of samples. The defects outlined above are avoided using these measures.

Title: Scale set for the rotary setting of machine parts
Inventor: GANTER BERNHARD
IPC: G05G1/10
Filed: 1983-12-20
Abstract: The scale set for the accurate rotary setting of machine parts which can be adjusted by spindles consists of a setting ring which is rotatably mounted in a frictionally engaged manner on a rotatable shaft. A groove of enlarged diameter is arranged in the bore of the setting ring. Seated in the groove is a flexible, first ring which radially to the inside carries a rigid, low-wear, second ring, the inside diameter of which is less than the diameter of the bore of the setting ring. The setting ring thereby sits on the outer periphery of the shaft, low-wear rotation being possible on account of the material properties of the setting ring, whereas the flexible, first ring merely produces the prestressing force, directed radially inwards, for the second ring.

Title: Exhaust-gas siren for a power saw
Inventor: SEID MANFRED
IPC: B27G19/00
Filed: 1984-06-26
Abstract: In order to increase working safety in the forest, power saws which are used in felling work are equipped with an exhaust-gas siren. This siren generates a sound pressure level which is clearly perceived even when ear protection is worn. The frequency is selected such that the warning tone stands out clearly from the background noise. The warning tone thus generated is intended for co-workers who are in the felling and fall areas. The warning shout of "look out" or "timber" which is required by the accident prevention regulations can thus be dispensed with.
